摘　　要：为提高航天器空间碎片防护结构的防护性能,减小其发射体积,提出了一种可折叠发射的屏间充气展开式多屏防护结构,通过充气展开支撑管在轨充气展开,成型为多屏大间距防护结构。分析了展开式多屏防护结构的空间碎片防护性能,得到了屏间距对多屏结构防护性能的影响规律。结果表明:在相同面密度下,展开式多屏防护结构的防护性能显著优于单屏防护结构,且其防护性能随屏间距的增大而提高。To improve the protective performance of the spacecraft space debris protective structure and to reduce the launch volume,an inflatable deployment multi-shield protective structure that could be launched in folded state was proposed.It could be deployed to an inflated multi-shield and large-spacing protective structure on-orbit.The space debris protective performance of the inflatable deployment multi-shield protective structure was analyzed and the influence of the shield spacing on the protective performance of the multi-shield structure was obtained.The results showed that the protective performance of the inflatable deployment multi-shield protective structure was significantly better than that of the single-shield protective structure under the same surface density,and the protective performance increased with the increase of the shield spacing.
